"No, I do not want toys."
Translation:Nac ydw, dw i ddim eisiau teganau.
The only letters that can be doubled in Welsh are n an r but many Welsh speakers have difficulty remembering the rules as to when you should double or not. So you end up with common spelling mistakes like cwestiynnau, carregog, tegannau etc., none of which need the doubling. Whoever wrote the question made a little mistake, that's all. If you look the word up in a dictionary it's teganau.
